Coposit: From financing concept to 10,000 users in six months.

Coposit wanted to change how first-home buyers secure property. Before the platform existed, the founders needed a way to turn a novel financial model into a working product that buyers and developers could trust. In the first development trial, the platform sold 85 of 97 apartments.

Coposit: From financing concept to 10,000 users in six months.

Meet Coposit

Coposit tackles the hardest barrier in property ownership: the upfront deposit. Founded by brothers Chris and Daniel Ferris — both property developers — the company was born out of a pattern they saw repeat across projects. Buyers struggled to assemble large deposits while developers waited months for presales to unlock financing. Prices kept rising. The entry barrier kept moving further out of reach.

The model was sound. The product didn't exist yet.

Four problems stood between the idea and the product

The Coposit model depended entirely on trust. Buyers needed to feel confident their deposits were protected. Developers needed certainty that applicants were legitimate and financially viable.

The founders had the business concept. They didn’t yet have the product.

Unclear Product Path

Chris and Daniel had no experience building apps. The idea was strong, but decisions around design, architecture, and technology carried long-term consequences.

Opaque Development Agencies

The founders approached several development agencies to explore the idea.

Responses were slow. Conversations were brief. Technical processes were rarely explained in detail.

High-Risk First Build

Coposit wasn’t a typical property platform. The model involved financial verification, buyer-developer matching, and long-term deposit management.

No Framework for Decision Making

Without experience in software development, the founders lacked the context to judge whether proposals were realistic.

Everyone we spoke to was slow to respond, brief in their interactions, and secretive about what was involved. After a while, we thought that was just standard industry practice.

The Coposit idea had real potential. But without a clear development process or a partner willing to explain the path forward, the founders struggled to move from concept to product.

They almost didn't do it

The founders were enthusiastic about the concept, but starting the build still felt risky.

The first version of the product would shape how developers and buyers perceived the model.

What does good look like in app development?
How do we protect IP and get to market quickly to ensure maximum market share?
What if we launch too quickly and damage our reputation early?

Instead of rushing into development, the project began with structured discovery. The goal was simple: understand the entire buyer journey before writing a line of code. That decision to slow down before speeding up is what made the first release land the way it did.

Before putting pen to paper - we listened

Before a single screen was designed, the EB Pearls team spent time understanding the concept end-to-end. Coposit were the experts on the property deal side, so they led the conversation. We listened.

The early discovery sessions focused on the core Coposit experience: how a first-home buyer moves from curiosity to securing a property. That journey surfaced questions no one had answered yet.

★ the reframe • built to last™ The Right Problem

The problem wasn't financial planning. It was trust.

The solution reframed the challenge: instead of waiting years to save a full deposit, users could start with a smaller entry point and build toward ownership — with every step visible, verified, and protected.
The platform was architected for scale from day one, ready to absorb rapid user growth without disrupting the buyer journey.

Built around the outcomes, not the software

The resulting platform focused on simplicity for buyers while giving developers the tools to manage applications and sales activity.

Six key components formed the initial release.

Buyer Mobile App

Where first-home buyers browse participating developments and apply using the Coposit model. Designed so that someone with no property experience can complete an application in under 10 minutes.

Developer Mobile Interface

A companion interface for developers to review applicants and manage property allocations.

Identity Verification Integration

API integrations with ID verification providers ensured applicants were genuine before progressing through the application funnel.

Customer Journey Optimisation

Implementing software like MixPanel, Coposit continuously refined the application funnel based on analytics and user behaviour.

Admin Analytics Dashboard

A reporting dashboard that tracked buyer behaviour and conversion metrics across the application journey.

Applicant-Developer Matching Engine

A system that paired eligible buyers with participating developments based on project availability and buyer eligibility.

Building Trust in a New Buying Model

01 Introducing a new way to buy property Users were unfamiliar with structured deposit alternatives and needed clarity before adoption.

02 Designing for financial sensitivity Every interaction needed to feel transparent and reliable due to high-value decision-making.

03 Supporting rapid early growth The platform had to handle sudden user adoption from launch without performance issues.

04 Balancing simplicity with financial detail Information had to be simple enough to act on, but detailed enough to build trust.

Three moments that earned their trust

The Coposit founders had spoken with agencies before the EB Pearls engagement. What stood out wasn’t just technical capability.

It was the way the team worked alongside them.

Transparent Roadmapping

The Roadmap session broke down the full development process, including expected timelines, phases and cost ranges.

For the first time, the founders could see the entire journey from concept to launch.

Weekly Decision Meetings

Coposit participated in weekly project meetings where technical decisions were explained and discussed.

Architecture choices were made collaboratively rather than hidden behind technical jargon.

Detail From Proposal to Launch

From the proposal stage onward, every step of the process was explained in detail.

The founders felt informed rather than excluded from the technical conversation.

From Interest to Ownership Momentum

Once Coposit went live, user behaviour shifted from passive saving to active property engagement.

5.0

One of the biggest differences was visibility. We always knew what was happening, what decisions were needed, and what was coming next. We were never left chasing updates or wondering where things stood.

Chris Ferris, —Co-Founder

The upfront deposit stopped being a barrier. It became a pathway into property ownership.

“I felt like buying a home was always years away.”

“Now I can actually see a way to start.”

The Coposit platform turned a conceptual financing model into a working marketplace connecting buyers and developers.

First-home buyers could browse developments, apply through the app, verify their identity, and secure property without paying the full deposit upfront.

Developers gained a new channel for converting interested buyers into committed purchasers.

The early Civic Properties trial demonstrated the concept in practice: 85 of 97 apartments sold using the platform.
